This result of the case Smith vs Pimlico Plumbers Ltd may assist claimants. That case went on for nearly a decade ending up in the Supreme Court I believe. Mr Smith was self-employed but treated like an employee, having to wear a company uniform and drive a company van. The end result was something along the lines of Pimlico wasn’t a genuine client or customer because of the contract arrangements and the way things were arranged being more like an employer-employee relationship. Mr Smith was entitled to holiday pay for the duration of his employment.
